12 October 2002: A bomb explodes in a Bali nightclub killing 202 people, many of them Westerners.

Islamic group Jemaah Islamiah (JI) is blamed for the blasts. In the months following the attacks about 30 alleged JI members are arrested and put on trial.

In October 2003, Mukhlas, also known as Ali Gufron, described by prosecutors as the co-ordinator of the bombings, was sentenced to death by an Indonesian court.

While the precise nature of JI's relationship with al-Qaeda is not known, many analysts believe informal links between the two organisations have grown in recent years.

5 August 2003: Twelve people die in a bomb attack at a US-run luxury hotel in the Indonesian capital Jakarta.

Indonesia's defence minister blames Jemaah Islamiah militants for the attack and reiterates the view that JI has links with al-Qaeda, saying that JI members had trained with the group in Afghanistan and Pakistan.

16 May 2003: Casablanca is hit by a series of suicide bombings that kill 41 people, including 12 attackers.

Moroccan authorities say that the attacks are linked to "international terror". Four men convicted and sentenced to death in September for the attacks are said by the Moroccan authorities to be members of the Salafia Jihadia. This group is widely believed to be linked to al-Qaeda.

12 May 2003: At least 34 people are killed in a series of bomb attacks in Saudi Arabia's capital Riyadh. The attacks were carried out against luxury compounds housing foreign nationals and the offices of a US-Saudi company.

The US and Saudi Governments say al-Qaeda is the prime suspect for blasts, which coincide with a visit to the kingdom by US Secretary of State Colin Powell.

8 November 2003: A bomb attack on a housing complex in Riyadh bears all the hallmarks of al-Qaeda, senior US and Saudi officials say.

Seventeen people are killed and more than 100 injured in the blast, mostly foreign Arab workers.
